Octopus does, as we would predict, live close to the limits set by its own physiology. The circulation, to take one example, is barely adequate for such an active animal, mainly because of the absence of any system for pack­ aging the blood pigment; haemocyanin in solution is a poor oxygen carrier. Cephalopod blood can transport less than 5 millilitres of oxygen per 100 ml of blood (compared with about 15 vol% in fish) and the whole supercharged system of triple hearts, high blood pressure and pulsating blood vessels succeeds only in returning blood that retains less than 30% of its dissolved oxygen by the time it reaches the gills. This at rest; the effect of exercise is immediate and surprisingly long­ lasting even in octopuses as small as 300 g, which must very swiftly run into oxygen debt when they flee from predators or pursue their prey (Sections 3. 2. 2, 3. 2. 4). Digestion, too would seem to be limiting. As with other molluscs, digestion in Octopus is based on secretion­ absorption cycles by a massive diverticulum of the gut, an adequate system in a less hectic past, but scarcely appropriate in a predator that must be an opportunist in the matter of feeding. Octopus feeds mainly at night, and spends a great deal of every day sitting at home. \u003ch3\u003eBook details\u003c\/h3\u003e\u003ctable style=\"border-collapse: collapse; width: 100%; \"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eSKU\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003eNLS9789401724708\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eISBN 13\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003e9789401724708\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eISBN 10\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003e9401724709\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eAuthor\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003eM J Wells\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eCondition\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eBinding Type\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003ePaperback\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003ePublisher\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003eSpringer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eYear published\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003e2013-11-20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eNumber of pages\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003e417\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 10px; border: 1px solid #ddd; \"\u003eCover note\u003c\/th\u003e\n\u003ctd style=\"padding: 6px 10px; border: 1px solid #ddd; \"\u003eBook picture is for illustrative purposes only, actual binding, cover or edition may vary.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Springer","offers":[{"title":"Default Title","offer_id":67735450878197,"sku":"NLS9789401724708","price":39.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/8632\/8821\/files\/9789401724708.jpg?v=1792242026","url":"https:\/\/arbiyas.com\/products\/octopus-by-m-j-wells-nls9789401724708","provider":"Arbiyas","version":"1.0","type":"link"}
